Part III - Data collection using a Soectrophotometer (Use this table if students Were unable fo complete the excrcise on taking Absorhance readings insing colored solutions)-This graph must be hand drawn You have a set of food extracts (colored solutions) in front of you, Pick one of the food extracts, take the absorbance readings at different wavelengths, using the spectrophotometer, and record the values in the chart below. Then, answer the questions below and plot a graph using this information, to complete the assignment in class or as homework. PICK ONLY ONE OF THE ABOVE: Extract you picked: Rad water Write the absorbance values below
Sfudent Activity Which extract did your group select? Review the information about the spectrophotometer and your answers to the above questions. What do you think will happen when you measure the absorhance of the extract in the spectrophotometer? Your answer to this question should be testable and falsifiable. This is your hypothesis for this experiment. Hypothesis Data Collection When designing an experiment it is important to think about bow you will record the data you will be collecting. Often the data are recorded in a table and then presented in a graph. Graphs provide a compact method of synthesizing all of the data into a single image (http.//www.ncsu. Graphing vour Results a. What is the independent variable? i. Does this go on the X-axis or Y-axis? b. What is the dependent variable? i Does this go on the X-axis or Y-axis? c. What kind of graph would be best to use?
